Overview of Kenaf Industry in Malaysia
The developing of kenaf industry is reflected by two important
events:The transformation of (MNTB) to Malaysian National Kenaf and Tobacco Board (MNKTB) and the inclusion of kenaf industry as one of strategic industries under the East Coast Economic Region (ECER) Development Program
Malaysian government has taken the initiative to focus on the development of kenaf-based products by integrating the upstream to downstream processing R&D, towards economic and marketing activities
Kenaf Fibre Processing
Infield Processing (decortication) (MNKTB)
Whole stem to long bast and water retting
Hammer mill processing (KFI Sdn. Bhd.) Whole stem to short bast and core fibre (10 -20mm),
Pulverizing process (Polyregion Sdn. Bhd.) Chip fibre to fine fibre (0.2-1mm)
It has been designed to provide less clogging and efficient mixing of kenaf and plastic in order to achieve desire fibre loading using various fibre mesh by applying continuous feeding system
The feeding rate study was conducted to identify relationship between fibre mesh and the highest potential fibre loading
The optimization processing condition was examine to determine the suitable feeder speed, main screw mixer speed and mixing temperature.
